At the same time, a second lifeguard called 911 while a third guard followed protocol and cleared both pools.

A fourth guard was radioed and arrived on deck to assist.

When the ambulance arrived, the child was responsive and taken to hospital.

The boy was kept in hospital overnight for observation, but was home the next day.

Two days later, he was back at the pool for swimming lessons.

“This incident is a reminder that we need to be vigilant with children when around water, especially with children under the age of seven”, said Lefebvre.

“The aquatic centre’s rules require children under seven years of age to be within arm’s reach of someone 16 years of age or older at all times. Drowning can occur in as little as 15 to 30 seconds.”
